by order or randomly?

 

If you mean by order, the first 12 records are to be one then:

 

data want;
   set have;
   if _n_ le 12 then variable=1;
   else variable=2;
run;

_n_ is a SAS automatic variable that counts iterations of a data step. In a simple use like this it is basically the row number.
